413-acre lake in Sudbury District, Ontario. The lake tops out around 30 ft. The depth data here comes from an MNRF lake survey by the Ontario MNRF. The season-by-season read for each species follows, from the map's own numbers.
When the water first warms, lake whitefish slide up into 9 to 30 ft. There's no big seasonal slide here — summer means 9 to 30 ft, winter 9 to 30 ft. If you only fish one area, make it Deep basin: a deep basin around 29 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a blade bait vertical or a small jigging spoon rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 9 to 30 ft | midday & dawn | Break off the point (8 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 9 to 30 ft | dawn | Deep basin (29 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (8 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 9 to 30 ft | midday & dawn | Deep basin (29 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Early season walleye use the shallows, holding in 4 to 15 ft. Summer is a 9 to 30 ft game here, winter a 9 to 30 ft one. The chart's best answer is Deep basin — deep basin, 29 ft, prime for winter. Best bite is the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.

A bucktail or a weedless spoon over cabbage covers the summer program.
